One embodiment oi the present invention is shown. in the accompanying drawings, in. which I Figure 1 is an elevationofi pained nolls employed in shaping the bees above men.- tioned, constructed: and arm in. scoordr ance with the present invention; Fi 2 is a side view, partly in section of imroved roll, t e section being taken. on. the so ine 2-2 in Fig. 1; Fig. 3.isa cnoSB seotion taken on the line 33 n Fig. 1; Fig?! is a cross soctinmtekpn-qmthelinq tr-Aim, ig, 1.; Fig. 5 is a detail viewshow ng a. fragnent. f the roller bearings; Fi 6 1s stepsiste a fragment of the bar mm wh ch horse are made, for the construction of oh the present ap aratus is designed; ig. 7 is a longitudina section take'n on the line 7-7 in Fig, 6., 1 4 The product'ot rolls of the classto which. the present invention belongs is shown substantinlly in Figs. 6 and 7 of the drawings. Lon bars of metal 15 have imparted there:

to e ongated depressions or creaseslti; in

st which, when the horseshoe 'is secured-to the hoof of the animal, the heads of the sec'ur-' ing nails are disposed. The bottom of the creases 16, as shown particularly in-Figii'l. of the drawi is waived to 'rovide t in sections 17, w ich are punche through to form holes for the nails by which the said shoes are secured to the boots of thaanimal. The creases 1,6 are arranged mm, as shown in-Fig. 6 of thedrawings. sari-- one pairs are divided, and the median line .constructiorifithehars 15 are fed by the roll or downward, hwessitsting aye-hen 2g nicks 18. The nicks 18 are disposed so at when the bar 15 is separated into short segments, the ends having. :1 portion 05 snid nicks see shaped to form the heels ot the 60 completed shoe.

It willbe understood. that when the straight bar, either in the shape of'shent sectionsor complete bar lengths, isconwented into shoes, these are shape aboutthe form 05 by being bent edgewis'e, the-openi .of the creases 16 being in position: to co the =ground when the shoe IS in service.

What may be termed the final or finishing step in. the-operation-isthat where'the bars m p'a-ssed'between'. a grooved or female roll 19 and a die or male roll 20. The roll 20- uegietens with the groove 21' of the roll 19, to sink between the uEper 'edges'of the side walls thereof. The at, when passed he- 5 tween these rolls, is sufficiently hot to rosdily change its shape, which. however, is prev served. in the passage by the side wnlis and. bottom of the groove 21 and; the top or crown. wall of the die 20., After psesing'heso 'tweemtlio female roll 19 and. male roli: 20, the bnir is returned) between the grooves: or female roll 22 and lihsmale roll; 21%,, where said; ban receives itsfinal'she in. cnoss sention, and is thereafter coo eds, needs: tier as transhipment on handling.

served that the variation in peripheral travel of said rolls operates to produce a friction or resistance to the advancement of the bars.

' To overcome the above objection, I form the roll 20 as a separate ring 26. The ring 26 is rotatable on the shaft 24:, the anvil section 27 whereof is provided with an annular groove to form a bearing for small rollers 28. The rollers'28 likewise extend below the tubular body 29- on which. is formed the male roll 23. The rolls 20 and 23 are spaced apart, as shown best in Fig. 2 of the drawings, and are held in position by rings or collars 30, forming end-thrust bearings for said rolls. Corresponding bearing rings 31 are provided to receive the thrust of balls 32, which, in conjunction with holding rings 33, form a thrust bearing for the rolls 20 and 23. The anvil section 27 is provided with a shoulder 34, to resist the thrust of a clamp nut 35 when. exertedto press upon the ring 31 and intermediate members, including the rolls 20 and 23. A nut 35 and a follower nut 36 are mounted upon a screw-threaded section 37 with which the shaft'2 i'is provided, see Fig. 2 of the drawings.

The rollers 28 have each tapered ends 38, to receive which, undercut grooves 39 are formed The overhanging wall of one of said grooves is unbroken. The overhanging wall 40 of the opposite groove is parted to permit the passage downward of one of the rollers'28. The opening thus formed in the overhanging wall 40 is closed, when in service, by a screw 41, as seen best in Fig. 5 of the drawings.

It will be observed that when thus*constructed and mounted, the. roll 20 and ring whereof travels in unison'with the engaged surface of said bar; or, in other words, they roll 20 rotates as an idler at a speed uniform with the engagedsurface of the bar 15. By

reason of this construction, the opposite surfaces of the bar travel at the same rate of speed, and the slippage, curling and misregistering of the points 25 above referred to, do not here occur. Likewise, the die sections 42 with which the roll 20 is provided perfectly reg'ster with the bars 15, irrespective of the iameter of the rolls 19 and 20.

It will also be observed that the sensitive bearing 'formed by the rollers 28 and balls 32 reduces the friction or drag of the ring 26 and the tubu'lar 'body 2 9 of the roll 23,- thus reducing the required amountpf manual exertion, and avoiding the consequent curling of the bar 15.

I claim- In combination, agrooved pressure roll, I

and a freely rotating die roll operating in conjunction with said pressure roll, to be moved thereby in unison therewith when frictionally engaged by an interposed article 'under treatment. f

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
